feat(app): add Nostr identity login via NIP-07 browser extension

Create useNostrIdentity.ts composable with NIP-07 window.nostr API
integration (getPublicKey, signEvent, extension detection). Add npub
bech32 encoding to bech32.ts. Create NostrLogin.vue settings component
with login/logout, npub display with copy, and extension install guidance.
